The invention belongs to the field of electric vehicles, and discloses a remaining driving range determination method and device. The method comprises the following steps: acquiring an actual driving attenuation coefficient of a previous journey; in the travel process, according to a preset display period, the current battery load state SOC of the vehicle battery corresponding to the current display period, the influence coefficient corresponding to the current vehicle operation information and the influence coefficient corresponding to the current battery operation information are obtained; and according to the actual driving attenuation coefficient, the current SOC, a preset full-power driving mileage, the influence coefficient corresponding to the current vehicle operation information and the influence coefficient corresponding to the current battery operation information, determining the actual remaining driving mileage corresponding to the current display period. By adopting the method, the accuracy of calculating the actual remaining driving mileage can be improved.

    本申请属于电动汽车领域,公开了一种剩余续驶里程的确定方法和装置。所述方法包括:获取上一行程的实际行驶衰减系数;在本行程过程中,按照预设的显示周期,获取当前显示周期对应的车辆电池的当前电池负荷状态SOC、当前车辆运行信息对应的影响系数和当前电池运行信息对应的影响系数;根据所述实际行驶衰减系数、当前SOC和预设的满电续驶里程、所述当前车辆运行信息对应的影响系数和所述当前电池运行信息对应的影响系数,确定当前显示周期对应的实际剩余续驶里程。采用本申请可以提高计算实际剩余续驶里程的精确度。
